[0001] This utility model relates to the technical field of hot melt adhesive powder collection equipment, specifically a collection device for the production of hot melt adhesive powder. Background Technology

[0002] Hot melt adhesive powder is a solid granular adhesive with thermoplastic polymer materials as its main components. It has the characteristics of bonding after heating and melting and rapid curing after cooling. In the production process, the thin strips of molten material are cut into granules by a pelletizer. A certain amount of hot melt adhesive powder is generated during the cutting process. This powder needs to be collected by a collection device to reduce material loss. A good collection device can improve the material collection rate and bring good benefits to enterprises.

[0003] In the production process of hot melt adhesive powder, the granules and powder are collected together by the collection equipment and then transported to the screening equipment for screening. Because the particle size of the powder is smaller, it is difficult to screen out. At the same time, some powder is scattered in the workshop with the airflow during the cutting process, resulting in material waste, causing certain economic losses to enterprises and causing trouble for users. We propose a material collection device for hot melt adhesive powder production. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5This utility model provides a technical solution: a material collection device for hot melt adhesive powder production, including a collection bin 1, a top cover 2, an inner cylinder 3, and a negative pressure fan 5. An outer cylinder 12 is embedded in the middle of the inner wall of the collection bin 1, and reinforcing ribs 11 are welded to the connection between the collection bin 1 and the outer cylinder 12. The inner cylinder 3 is embedded in the inner wall of the outer cylinder 12, and a filter screen 31 is laid around the inner wall of the inner cylinder 3. A top cover 32 is embedded in the upper end of the outer cylinder 12, and a feed head 33 is injection-molded at the top of the upper end of the top cover 32. The lower end of the collection bin 1 is movably connected to... The storage compartment 1 has a support frame 4. A negative pressure fan 5 is mounted on the upper end of the support frame 4, and the connection between the negative pressure fan 5 and the storage compartment 1 is screwed onto a mounting plate 51. A top cover 2 is movably connected to the top of the storage compartment 1, and a middle cover 22 is embedded in the middle of the upper end of the top cover 2. The connection between the middle cover 22 and the top cover 2 and the storage compartment 1 is screwed onto a hinge 21, and a semi-circular groove 23 is provided at the connection between the top cover 2 and the middle cover 22. A connector 25 is fixedly connected to the lower end of the middle cover 22, and a sealing strip 24 is glued to the lower end of the top cover 2. Furthermore, the sealing strip 24 is interference-fitted to the upper inner wall of the storage compartment 1. A round hole 26 is provided at the connection between the top cover 2 and the connector 25, and the feed head 33 is distributed along the lower end of the round hole 26. The top cover 2 serves as the upper sealing component of the storage compartment 1, connected to the storage compartment 1 via a hinge 21, satisfying the user's need to open the cover and retrieve materials. Simultaneously, the top cover 2 also has a round hole 26 directly connected to the hot melt adhesive powder production equipment. This round hole 26 is sealed by the middle cover 22, which is also movable. The device connects to the top cover 2 via a connection method that is convenient and practical. During the hot melt adhesive powder production process, the powder falls and is collected and stored centrally by negative pressure suction, reducing the distribution of powder in the workshop and lowering the loss rate of hot melt adhesive powder production. In order to reduce the leakage of material from the storage bin 1, the top cover 2 is equipped with a sealing strip 24 at the connection gap between the storage bin 1 and the top cover 2. The sealing strip 24 can reduce the leakage of adhesive powder from the gap in the storage bin 1.

[0023] Telescopic cylinders 13 are symmetrically distributed on both sides of the outer cylinder 12 in the storage compartment 1, and the telescopic cylinders 13 and the storage compartment 1 are fastened together with screws. A buffer pad 14 is movably connected to the top of the telescopic cylinder 13, and the buffer pad 14 fits snugly with the top cover 2. The reinforcing rib 11 is a welded part, and its two ends are connected to the outer cylinder 12 and the storage compartment 1 respectively. The connection has high strength and stable structure, which can meet the long-term use of the outer cylinder 12 and the storage compartment 1. The outer cylinder 12 is the load-bearing component of the inner cylinder 3. Both of them have through holes on their inner walls. A filter screen 31 is laid in the through holes. The pore size of the filter screen 31 is smaller than the particle size of the powder, which can effectively meet the needs of the inner cylinder 3 to collect the powder. The storage compartment 1 is also equipped with a telescopic cylinder 13. The telescopic cylinder 13 is a traction buffer component to reduce the situation of the top cover 2 being closed violently, improve the service life of the overall equipment, and the telescopic cylinder 13 can play an auxiliary guiding role in the opening operation, which can bring convenience to the user.

[0024] The lower end of the storage bin 1 has U-shaped grooves 15 on both sides. The connection between the support 4 and the storage bin 1 is bolted to a movable arm 42. A handle 41 is welded to the end of the support 4 away from the movable arm 42, and the handle 41 is embedded in the U-shaped groove 15 with an interference fit. Through holes are provided around the inner walls of the outer cylinder 12 and the inner cylinder 3, and the bottoms of the outer cylinder 12 and the inner cylinder 3 are aligned with the negative pressure fan 5. This structure collects powder materials through negative pressure suction. The equipment is simple to operate and has a wide range of applications. The negative pressure fan 5 has a wide range of functions, which meets the user's needs for integrated collection and processing of hot melt adhesive powder. The bottom of the negative pressure fan 5 is equipped with a support 4, which suspends the bottom of the storage chamber 1 to ensure that the airflow can flow well from the bottom of the storage chamber 1. At the same time, the support 4 adopts a movable structure to connect with the storage chamber 1. By pressing down the handle 41, the handle 41 drives the support 4 to rotate axially around the center of the movable arm 42 until the support 4 rotates to the other side, thereby achieving the requirement of fully opening the bottom of the negative pressure fan 5.

[0025] Working Principle: For this type of collection device used in the production of hot melt adhesive powder, the middle cover 22 is rotated and separated from the top cover 2 at the semi-circular groove 23. The connecting joint 25 separates from the round hole 26, opening the round hole 26. The user connects one end of the corrugated pipe to the round hole 26 and the other end to the material discharge end of the hot melt adhesive powder production equipment. At this time, the negative pressure fan 5 blows air outward, creating a negative pressure state inside the collection chamber 1. The airflow is replenished through the round hole 26 and flows in through the through holes of the outer cylinder 12 and inner cylinder 3 until it is discharged from the bottom of the collection chamber 1. Through this airflow trajectory, and by using negative pressure suction, the hot melt adhesive powder is continuously collected. The hot melt adhesive powder is continuously drawn in and then intercepted by the filter screen 31 at the inner cylinder 3 and outer cylinder 12, falling into the inner cylinder 3. When the inner cylinder 3 collects a certain amount of powder, and the powder is completely settled, the user removes the corrugated pipe, closes the middle cover 22, and its connector 25 seals the round hole 26. Finally, the telescopic cylinder 13 pushes out, and the buffer pad 14 drives the top cover 2 to rotate axially along the hinge 21 until the top cover 2 rotates to the limit position, at which point the upper part of its collection chamber 1 opens, and the inner cylinder 3 is pulled away from the outer cylinder 12 to collect the powder. Then, a new inner cylinder 3 is taken out and replaced, and the above operation is repeated to continue collecting the powder.
